FIELD OF THE INVENTION

The present invention relates to a one piece re-closable unit pack such as blister pack and method of manufacturing the same. Further the said re-closable and lockable blister pack is optionally constructed to provide child resistant capability and/or unique identifiers to aid in establishing the authenticity and genuineness of a packaged product.

BACKGROUND OF THE INVENTION

Packs such as blister packs that comprises of one or plurality of deformable protrusions formed in a flexible sheet with a closure for each of the protrusions are primarily but not exclusively used to packaged in products such as medicaments. Products in blister packs are either sold as such or are generally encased in a container for extra protection during transportation and handling. The container serves multiple purposes like providing protection to the blister pack(s), serve as a substrate to display product information and/or usage instructions, lockable provisions to serve as child resistant packs, etc. Further, establishing the authenticity and genuineness of a packaged product is essential as counterfeited products when consumed can cause grave harm to the end users.

U.S. Pat. No. 5,954,202 discloses a Paperboard blank for a self-contained, reclosable package. It relates to paperboard blanks which are used to form self-contained, reclosable packages. Structures of this type, generally, are comprised of one piece of paperboard that when folded act as an outer package when sealed and an innovative reclosable package after being opened.

U.S. Pat. No. 6,047,829 discloses a unit dose packaging system (UDPS) having a child resistant locking feature. The invention relates to a two piece paperboard package that houses a unit dose product on an internal slide card within an outer paperboard shell. This package may have one or more internal or external lock(s) that prevent the slide card from being pulled out without triggering some type of lock release mechanism. This package is focused around providing a child resistant, senior-friendly unit dose package that can be opened and closed numerous times and then finally disposed of.

There is an unfulfilled need in the market place for single piece re-closable packages especially blister packs that do not need additional encasing systems and are yet capable of being child resistant. Additionally, many clinical indications require the patient to take limited dosages and hence the packaging must be tailored to meet such a need so as to ensure patient compliance and also avoid wastage of the medicines, yet has the capability of being re-closable and also eliminating the need of additional carton/closure to encase/house the pack along with optional child resistant characteristics. Further, it is desirable to provide such single piece re-closable child resistant packs with unique identifiers to aid in establishing the authenticity and genuineness of a packaged product and for diverse applications including anticounterfeiting, pharmaco-vigilence in clinical trials, enhancing patience compliance, etc.

 8. A single piece re-closable unit pack as claimed in claims 1-7 comprising a central triangular portion provided with an opening at one of the corners, three triangular portions disposed along the three edges of the said central portion wherein the first portion is foldably disposed such that the first layered structure as claimed in claim 1 in which one or plurality of enclosed spaces containment(s) are formed to contain the product(s) is in the same plane and upper surface side of the central planar portion, an engaging provision that projects from the first planar portion; the second triangular planar portion that is foldably disposed along the second edge of the said central portion in such a manner that the enclosed spaces containment(s) up stand on the opposite face of the said central portion, that is the second repturable layered structure adjoins the upper surface of the said central portion; the third triangular planar portion that is foldably disposed along third edge of the said central planar portion wherein this planar portion is provided with a receiving provision in the form of a slot at the base and a stripe extended from the apex wherein the third said planar portion is folded such that it overlays on the said central portion such that the containment(s) are on the upper surface and the first portion is folded so as to overlay on the capsule side of the said third planar portion wherein the containment(s) of the first portion are disposed in a manner with respect to the containment(s) of the said third portion such that they do not overlap when the said portions overlay wherein the said stripe wraps around the three portions and fits in the said slot so as to hold the portions together when folded.
 9. A single piece re-closable unit pack as claimed in claims 1-8 wherein the fold comprises of perforations and/or scoring to facilitate fold/s.
 10. A single piece re-closable unit pack as claimed in claim 9 wherein the foldable region comprises of scoring wherein when folded the said region protrudes outwards in a convex profile.
 11. A single piece re-closable unit pack as claimed in claims 1-10 wherein the unit pack is provided with an identification tag for identifying the package for authentication wherein the tag comprises at least two sets of identification information, said at least two sets of identification information comprising a first set of identification information and a second set of identification information each arranged within a different surface, side or plane of the identification tag, and identification features of said first set of identification information and identification features of said second set of identification information are arranged at a fixed relative spatial position with respect to each other, said fixed spatial relationship being used for identifying the package system.
 12. A single piece re-closable unit pack as claimed in claims 1-11 wherein a reader means is provided to identify and read the unique identification information on the said package wherein the reader means is suitably able to detect the identification information relating to the product package and conveys the information or generates a signal in response to the information which is communicable to the external device. Suitably, the information is encoded and preferably is optical, electronic, magnetic or a combination thereof.
 13. A single piece re-closable unit pack as claimed in claims 1-12 wherein the pack is provided with a means to detect disengagement of the said engaging provision from the receiving provision to monitor and/or record of package and/or product access from the package system wherein the pack is provided with a wired/wireless communication means capable of interacting with external/remote device/s.
 14. A single piece re-closable unit pack as claimed in claims 1-13 wherein embedded system is adapted to fit in/on the said pack to detect disengagement of the said engaging provision from the receiving provision to monitor and/or record of package and/or product access from the package system wherein the said sensing means comprises of signal generating provision/s, data processing means, data logging and storing means configured with a communication means an optional communication switch, a power source, optional audio signal generating means, an oscillator wherein the said signal generating means gets activated upon disengaging the said package from the package holding provision wherein the activation of the signal generating provision may be done by various means such as electronic, mechanical, optical, visual.
